E9 - Rainier Valcarcel, Discipline Director, Cities Infrastructure @ Buro Happold
1mo ago · 41:39
Buro Happold designs some of the world's most ambitious city developments. From London's dense, centuries-old core to blank-canvas megaprojects in Saudi Arabia, its infrastructure teams sit at the point where climate resilience, mobility and carbon targets stop being separate conversations and become one design brief. Rainier Valcarcel has spent twenty years in that brief. He started his career in South Africa, moved to the UK eighteen years ago, and now leads Cities Infrastructure at Buro Happold, working across projects from Kingston's Mini Holland cycle scheme to Riyadh Expo 2030 and Qiddiy
E8 - Susanna Zammataro, CEO @ FIDIC
1mo ago · 48:28
Susanna Zammataro became CEO of FIDIC, the International Federation of Consulting Engineers, a year ago, arriving from 18 years building global road safety data at the International Road Federation. In this episode, she talks with Nicolas Miravalls about FIDIC's carbon management ecosystem, the shift toward multi-criteria procurement with the multilateral development banks, and why she believes AI adoption should start with governance, not tools. The honest takeaway: none of it works until the industry values its own expertise properly.
E7 - Louis Bettini, Principal Advisor Sustainability @ Main Roads Western Australia
2mo ago · 41:52
Louis Bettini grew up on a cattle station 60 kilometres from the nearest town, studied commerce, and spent the last 15 years leading sustainability at one of the world's largest road agencies, Main Roads Western Australia. He chairs PIARC Technical Committee 4.5 on Decarbonisation of Road Construction and Maintenance. In this conversation with Renaud de Montaignac, Louis talks through Western Australia's trickle-down procurement model for decarbonisation, a data-driven approach to network vulnerability assessment, six priority circular materials from recycled asphalt to green steel, and the re
E6 - Davide Lo Presti, Associate Professor @ University of Palermo
3mo ago · 57:16
Davide Lo Presti started his career with a bag of crumb rubber and a PhD question: could waste tyre material be meaningfully integrated into asphalt? Twenty years later, he is leading the SMARTI Lab at the University of Palermo, chairing RoadLCA — the International Symposium on Pavement and Bridge Life Cycle Assessment — and watching the research he began in Nottingham become mandatory in Italian procurement law. This episode covers the full arc: what it takes to move sustainable materials research into industry practice, why road authorities are the real lever of change, how to train engineer
E5 - Marta Bouchard, Sustainability Solutions Director @ Autodesk
4mo ago · 54:14
In this episode of Sustainable Infrastructure, we sit down with Marta Bouchard, Sustainability Solutions Director at Autodesk. Marta shares her journey from sustainability consultant to technology leader, and why she made the switch: impact at scale. We explore how Autodesk built an open partner ecosystem to bring carbon measurement directly into the tools engineers already use, and why no single company can solve infrastructure decarbonization alone. Marta breaks down the real barriers to adoption, the 33% variation problem in carbon calculations across the industry, and what comes after carb
E4 - Andreas Linnet, Global Decarbonization Lead for Infrastructure@
5mo ago · 52:21
In this episode of Sustainable Infrastructure, I sit down with Andreas Linnet, the Global Decarbonization Lead for Infrastructure at Ramboll. Andreas shares his journey into the world of decarbonization and discusses the pivotal role engineers play in optimizing design for sustainability. We delve into the importance of early carbon quantification in project planning, and how setting clear targets can lead to significant resource and cost savings. Andreas emphasizes the need for a systematic approach to carbon management, encouraging engineers to leverage available tools to make informed decis
E3 - Alice Yiu, Head of Advocacy and Outreach @ IRF
6mo ago · 53:25
Welcome to Episode 3 of Sustainable Infrastructure, the ORIS podcast where engineers, policymakers, and construction leaders share how the world can build infrastructure fit for the environmental and social challenges of the 21st century. Our guest is Alice Yiu, Head of Advocacy and Outreach at the International Road Federation (IRF), a Geneva-based not-for-profit representing the global road community across 118+ countries. Before joining IRF in 2025, Alice spent more than a decade at the SLOCAT Partnership on Sustainable Low Carbon Transport, where she represented the transport sector at UN
E2 - David Orr, Product Lead, Moata Carbon Portal @ Mott MacDonald
6mo ago · 49:40
Most infrastructure companies say they care about carbon. But how many actually measure it at the design stage? And of those who measure, how many actually act on the data? David Orr has spent the last three years answering these questions at global scale. As Product Lead for Mott MacDonald's Moata Carbon Portal, he has watched the platform grow from serving a handful of transport projects to supporting infrastructure assessments across 55 countries, spanning energy transmission, water networks, airports, and linear infrastructure. This isn't just another "we built a tool" story. It's a front-
E1 - Costanzo Graffi, Europe Contractors Partnership Lead @ AECOM
10mo ago · 45:16
In this inaugural episode of Sustainable Infrastructure, I sit down with Costanzo Graffi, Europe Contractors Partnership Lead at AECOM. We delve into the pressing need for the construction industry to embrace sustainability, exploring how early decisions can significantly reduce carbon footprints in infrastructure projects. Costanzo shares insights on AECOM's ambitious goal of halving carbon emissions across major projects and the vital role materials play in achieving these targets. We discuss the ecosystem of data and tools necessary for effective decision-making and the evolving landscape o
